A new study looks at the effect of climate change on the ski industry in Oregon and other western states. Winter recreation like skiing, snowmobiling, and snowshoeing make up a $12.2 billion industry. A bad snow year can cut that total by $2 billion.

Oregon is the state that suffers most in the Pacific Northwest when there is a bad snow year — the total number of skiers drops 31 percent. Washington sees 28 percent fewer skiers in bad years, and Idaho’s total drops by 17 percent.

Are you a skier snowshoer, or snowmobiler? Have you noticed a trend in snowfall and snowpack over the past decades? How have your snow seasons changed?
